Study on genetic variation and interrelationship of different quality characters was carried out using twenty-three recombinant inbred lines (RILs) of Sabita/Sambamahsuri derivatives developed at Regional Research Station, Bidhan Chandra Krishi Vishwavidyalaya, sub-centre - Chakdaha, Nadia, West Bengal along with four check varieties viz. Swarna sub-1, Dhanarasi, Sambamahsuri and Sabitain RBD with two replications. Grain yield and eight quality characters were studied and statistical analysis carried out for the estimation of GCV, PCV, heritability (BS), genetic advance and correlation coefficient for all characters. It was observed from grain quality performance that the genotypes S17 (81.235%) was superior in hulling percentage and S11 (69.235% and 59.825%) for milling percentage and head rice recovery. Among the selected genotypes, S1, S7, S9, S10, S12, S13, S18, S21 and S22 reported intermediate (20% - 25%) amylose content. Analysis of variance revealed highly significant differences among the genotypes for all the characters under study. Alkali spreading (26.667% and 27.657%) value exhibited highest estimates of GCV and PCV. High heritability coupled with high genetic advance as percentage of mean was observed for amylose content (99.310% and 43.201%), volume expansion ratio (98.985% and 36.493%) and alkali spreading value (92.970% and 52.967%). Grain yield plant-1 exhibited significant positive correlation with hulling percentage, milling percentage and head rice recovery and showed negative significant correlation with water uptake ratio and alkali spreading value. Therefore, direct selection would be effective for quality improvement of rice against these characters.
